请详细说明.--I wonder what makes you a successful manager?
--I wonder what makes you a successful manager?
--I as a waiter for five years,which contributes a lot to my today's work.
A served B,had served C have served
c 错了我理解,说是选A,但是为什么B错了,时态是在过去的动作在过去结束,并产生了影响,为什么不能选B?

我觉得是这样,理由有两点：1.题中没有明确的这5年时间是过去的过去,这是合理推断出来的,但是,在做题过程中合理推断得出的答案基本都是错的!一定要根据题中已说明的内容作答.2.for five years是过去的一个时间段,如果要用完成时态的话,也应该是i had been serving as a waiter for five years巴拉巴拉.（当然有这么一项我也不会选的,这表述也太繁琐了...）,直接用served 表示说明一个事实,我做过五年的服务员,这个经历对我的今天很有帮助.
过去完成时须有另一时间与其对照，题中无另一时间，故A
过去完成时表示过去某一时间或动作以前已经发生或完成了的动作。它表示动作发生的时间是“过去的过去”，而成为Manager这个事情并未发生在过去的过去。
